PC300HD-6 FLYWHEEL HORSEPOWER 173 kw 232 HP @ 1750 rpm OPERATING WEIGHT 35770 36630 kg 78,860 80,755 lb PC300HD-6 HYDRAULIC EXCAVATOR
PC300HD-6 Hydraulic Excavator WALK-AROUND The PC300 follows the strategy of offering the highest level of technological superiority and leadership in the industry. The PC300 introduces several new features to provide the operator with a smoother, faster, and more efficient machine. Combine these and you will know why over 90% of our customers gave an excellent rating for our excavator design and technology. Brass bushings High tensile strength brass bushings replace steel bushings at the boom foot and boom cylinder foot. Noise and play of work equipment are reduced. Multi-layer viscous cab mounts Vibration and noise in the cab are reduced and riding comfort is improved. Active mode, preferred by experienced operators, increases productivity up to 7% by matching the work equipment speed to the weight of the load and adjusting the speed, pump flow, and boom down speed. 2
PC300HD-6 HYDRAULIC EXCAVATOR Advanced Monitor Features Self-diagnosis of 119 different problems. Five working modes as standard, including breaker mode for maximum productivity. Active mode for increased implement speed. FLYWHEEL HORSEPOWER 173 kw 232 HP @ 1750 rpm OPERATING WEIGHT 35770 36630 kg 78,860 80,775 lb BUCKET CAPACITY.96 1.91 m 3 1.25 2.5 yd 3 Improved monitor Engine oil maintenance has been added as a function, and the default Work Mode can be changed. Hydraulic filter The hydraulic oil and filter replacement schedules have been increased, reducing maintenance. Emissionized engine at 173 kw 232 HP, it is one of the most powerful in its class. 3
PRODUCTIVITY FEATURES Power, versatility, maneuverability, controllability you name it. Never has there been an excavator so easy to operate, so natural, so intuitive, so responsive. HydrauMind allows the load-sensing and pressure compensating valves to automatically adjust to individual work applications. Adjustments are sensed by the valves. Electronic controls maximize the engine horsepower so full horsepower is available at all times. For example, when the ground condition changes while digging, you don t have to think about changing lever strokes because HydrauMind instantly, silently, and automatically sends just the right amount of oil to the actuators at just the right pressure to accommodate the change. Engine The new Komatsu SA6D114E-1 meets emission regulations, including CARB. New hydraulic pumps produce the same power as in the previous model at reduced engine speed. The new engine provides improved emissions without sacrificing valuable hydraulic power. Also, noise levels are reduced for improved operator comfort. In-Line Filtration The PC300 has a cool-running hydraulic system with the most extensive filtration system available. It uses a new high-performance filter glass for improved cleanliness and extended replacement interval. The wide variety of attachments available today means you put more stress on your excavator than ever before. Komatsu provides the extra protection for your machine by providing a highpressure in-line filter as standard equipment. When you move the boom, arm, and bucket at the same time, all the equipment works naturally, with the optimum combination of speed and power as if it were a human hand. HydrauMind also makes it easy to change or add valves and work equipment. 4
PC300HD-6 HYDRAULIC EXCAVATOR Easy Operation Self-Diagnostic Monitor Self-Diagnostic System The PC300 features the most advanced diagnostic system in the industry. Komatsu s exclusive system identifies 119 items, reduces diagnostic time, and helps you maintain maximum production. Working Mode Selection The Avance excavator is equipped with five working modes. Each mode is designed to match engine speed, pump speed, and system pressure with the current application. Working Mode Application Advantage Maximum production/power H/O Heavy-Duty Fast cycle times Power up/speed down available Good cycle times G/O General Good fuel economy Power up/speed down available F/O Finishing Smooth finishing capability Arm in 1 2 speed L/O Lifting Powerful lifting Power maximum pressure 100% of the time Reduced speed Precision control B/O Breaker Optimum engine rpm, hydraulic Operations flow, and pressure Power Up/Speed Down Switch* A button on top of the left joystick provides an instant burst of power at either full speed or half speed depending on the selection made on the monitor. Selection Application Result Power Up Tough Digging Increase implement force Operations by 9% for 8.5 seconds. Speed Delicate Speed is reduced by 1 2. Down Operations Increase implement force by 9% as long as joystick button is pressed. *Available in H/O and G/O mode only. Travel Speeds The Avance excavator is equipped with three travel speeds to provide smooth, efficient travel around the job site. Working Mode Power Up/Speed Down Travel Speeds Active Mode The Active mode increases engine speed, pump flow, and boom down speed to improve productivity up to 7%. Under light loads, equipment speed is faster. When under heavy loads it is possible to detect engine speed. The LCD portion of the monitor has four different display modes that aid in identifying potential problems before they become major problems: Four Diagnostic Modes 1 Time Display mode is the default mode and shows the time and hour meter reading. 2 User Code Display mode displays a trouble code and sounds an alarm when a problem has been detected. 3 Trouble Data Memory mode monitors 32 separate items and stores up to 20 abnormalities over 999 hours for effective troubleshooting. 4 Operation Data mode monitors 20 separate current operating conditions including system pressure and rpms to keep your machine operating at peak performance. In addition, 44-bit patterns allow you to diagnose electrical connections. Together these modes allow you to troubleshoot 119 different problems to minimize downtime. 5
